For ease of description only one projecting lug and interengaging grooveper telescoping section was illustrat described; however, any number atlugs and grooves in, tled to impart stability and strength to theinvention can used.

The fastening member d of HG. l is comprised of three steppedcylindrical portions, db Elli and in this ment, although any desirednumber of stepped portions may be provided, on the inside of which areprovided threads Sill, Elli adapted to threadably engage tlireads l7,.llil, 1255, respectively, on elements M, M, llli of connecting member asembly 3. Cylindrical portion 32 is provided with an euterlor thread 3bwhich is adapted to threadably engage three s M of the fastening means loil other hall of the invent so that the two fastening means may he theariably secured to one another as shown in FIG. 2. A groove 35; isprovided around the periphery of cylindrical section 31 and receivesloop 39 of carrying handle iii.

Maximum versatility and adaptability is provided by hinges 9 and i341connecting the two halves of top planar member 2 and the two halves ofbase planar member ll so that the two halves may be superimposed when itis desired to utilize the invention to carry a single stack as shown inHQ 2. Interlocking feet 41, 42 are provided on base planar member 1 sothat the two halves of base planar member 1 are securely held togetherwhen in the folded configuration. The cylindrical collar 28 plus the liplll serve as a base for the invention in this configuration to preventthe surface of base planar member it from resting directly on the floor.

In operation, if it is desired that a full load of carousel slidemagazines, six for this embodiment, be carried, the invention is placedin the configuration shown in FlG. l. The connecting member assembly 3is attached to the base planar member l. by threadably engaging theouter telescoping cylindrical member 13 and internally threadedcylindrical collar 28. The inner telescoping member 15 is pulled upwarduntil both it and member M have reached the extent of travel permittedby lugs 38 and 22 and grooves 19 and 23. The member 15 is then twistedin a counterclockwise direction, thus locking members 15 and lid intheir extended positions through engagement of lugs 18 and 22 and grooveextensions and 24. This procedure is repeated for the other half of theinvention so that both connecting member assemblies are fully extended.The first two carousel slide magazines 12 are then placed on theinvention so that cylindrical collars 28 are fitted within the centralapertures of the slide magazines. The remaining magazines are thenstacked on the first two magazines and the top planar member is placedover the top magazines so that the inner telescoping member 15 projectsthrough the central apertures 1 .20, 121 of each half 5, s of the topplanar member 2. The fastening means i is then threadably engaged withinner telescoping member 115 by means of threads 25 and 35. It should beunderstood that the same procedure must be carried out to secure theother half of the invention although for simplicity of description thisobvious step is not explicitly detailed herein. The dimensions of thecentral cylindrical collars 25 and of the top and base planar members 1and 2 are chosen so that the standard carousel slide magazine fitsclosely within the invention. The central cylindrical collars 28 andlips ill and ll prevent movement of the magazines during travel, and thetop and base planar members i and 2 and the sides of the magazinesprovide protection for the contents of the magazines in inclementweather.

If it is desired to carry four magazines, then the inner telescopingmember 15 is not extended, and the fastening device 4 is threadablyengaged with member M by means of threads 23 and 34.

in a similar fashion two magazines may be carried by threadably engagingthe fastening member 4 with the outer telescoping member 13 by means ofthreads 17 and 33. The inner telescoping members l4 and 115 are notextended in this configuration.

if it is desired to carry from one to three magazines in a single stack,the top and base planar elements l and 2 may be folded by hinge means 9and 134 to superimpose their respective halves. in this configurationthe connecting member assembly 3 from one half is removed and that halfof the base planar member 1 is folded over on the other half and isengaged by means of the interlocking feet 41, 2. The top planar memberis folded through hinge 9 and the invention is assembled for use aspreviously described. After one fastening means 4 is threadably attachedto the single connecting assembly 3 the remaining fastening means 4 isthreadably secured to the first fastening means 4 through engagement ofthreads 3d and 36. The carrying handle lli is in place over the twofastening means 4 for ease in carrying the invention in thisconfiguration. An alternative embodiment of this concept could beachieved through the use of hinge elements having a removable pivot pin.The pin could he removed from the top and bottom hinge elements so thatthe two halves of the carrying device could be used independently.Provision of an extra pair of fastening means would be required,however, unless the carrying handle 45) were made to be removable.

in EEG. 4 is shown an alternative embodiment of the telescopingconnecting member assembly 3. in this embodiment telescoping members 50,51, and 52 are provided with threads 53, 5d, and 55 at the outer topsurfaces of each respectively, threads 56, 57 on the inner top surfacesof members 50 and 51, respectively, and threads 58, 59, so at the outerlower surfaces of each, respectively. The telescoping members areextended and locked in place by means of thread pairs 57, 66B and 56,59. Thread 58 is used to attach the assembly to the cylindrical collars28 on the base planar assembly l and threads 53, 54 and 55 are utilizedto secure the fastening means 4 at the three stages of extension of theconnecting member assembly. This embodiment can be used directly inplace of the connecting member assembly shown in FIG. 3 and the samefastening means t can be used with it Without modification.

Another alternative embodiment of the wrmecting member assembly is shownin FIG. 5. hi this embodiment the telescoping members are locked intoplace when extended by means of peripheral grooves 70 and 7H and radiallips '72 and 73. Threads 74, 75, and 76 are provided on the outer topsurfaces of telescoping members 77, '78, 79 for attachment of fasteningmeans 43. Thread $0 on the outer bottom surface of member 77 is used toattach the assembly to the cylindrical collar 28 on base planar memberll. In operation the assembly is extended by pulling upward on thetelescoping member until it locks in place. The assembly is collapsed bypushing down on the topmost element. This embodiment can be useddirectly in place of the embodiments shown in FiGS. 3 and 4 and thefastening means 4 also can be used. The telescoping members may be madein a cylindrical embodiment or they can be constructed so that thebottom diameter is greater than the top diameter thus insuring that theelements cannot come apart if the groove and lip should becomedisengaged.

In FIG. 6a is shown another alternative embodiment of the connectingmember shown in FIG. 3. This embodiment consists of telescoping membersllllli, 102i, 102. Members ltill and 1102 are provided with internalgrooves MB, 1434 which engage inwardly projecting lugs 105, 11061 frommember 1 3%, Mil, respectively. Each groove is provided with extensionsW7, W8 perpendicular to the length of the grooves at the bottom of themembers 101, 102 to provide for locking when these members are extended.The grooves are also provided with an Lshaped extension ins, lit at thetop of the member so directed that when the projecting lug is in theright corner of the L-shaped projection an upward pull on the memberwill force the projecting lug down into the lower part of the L- shapedprojection as shown in FIG. 6b. In this position the telescoping memberis locked in to position and cannot move. Thus it is now possible to usea fastening means 13 ll with only one inner thread 112. The dimensionsof the members are chosen such that when the invention is in use anupward force will be exerted on the telescoping member, thus holdingthem securely and positively in position. A thread M3 is provided on theouter lower surface of member Mil to attach the assembly to cylindricalcollar 28 on base planar element 1. A

In FIG. '7 is shown a cloverieaf arrangement of my invention" adapted tostore four stacks of magazines. The various sections can be assembledfrom the members previously d scr bed. Th embodiment is intendedprimarily tor storage v ertendcd to include any convenient number of theinvention may be made from plastic, wood, or metal by any conventionalrnctnorl, although it is considered that injection molding from plosticmaterial will provide the most inexpensive satisfactory product. Anembodiment containing a rnaidiniun of three ertendible elements hm beendescribed herein for purposes of illustration as this size has beenfound to be most useful and convenient; however, extension of theenormity to any desired number of cirtendible sections can beaccomplished by application of the principles disclosed.
